vided with a switch rail or tongue .T, arranged to turn on apivot r. Thesaid switch tongue is mounted on the casting K in the usual way. A pin3, projecting from the tongue J through a slot t in the casting K,enters an arm a on the sliding rod L, placed in the switch pit below thetrack rail. To opposite ends of the said rod L, are secured cross bars11,1), carrying armatures w, 20', which enter the coils a, 0. of theelectro magnets M, M. The said magnets are furnished with short cores1), and areinclosed in lead to prevent them from being acted upon by anywater or moisture that may enter the pit.

The electromagnetic mechanism is inclosed in an iron box N, providedwith cross bars 0, 0', through which the rod L slides, and on the rod L,between the arm 16 and the said cross bars 0, O, are placed buffers c,to prevent shock when thearmatures are drawn in either direction.

To some fixed support, preferably near the track rail, and in the pathof the roller 19 of the contact maker E, are supported contact plates(1, (1 which are surrounded by insulation c. From the contact plate d awire f extends to the magnet M, while the contact plate (1 is connectedby the wire f withthe magnet M, and both of the said magnets aregrounded on the wire g. The box containing the magnets is closed at thetop by serrated covers in the usual way. \Vhen a car approaches a switchand the driver desires to open it, he depresses the rod 0, bringing thecontact roller 1) into contact with the plate cl, as shown in Fig. 1,when the magnet M is energized,and its armature and the rod L attachedthereto are drawn over toward the magnet, carrying with them the tongueJ, bringing it into the positionshown in Fig. 6. Shouldhe desire tochange the switch so as to cause the car to take the side track, hebrings the contact roller 1) into contact with the plate (1 thusenergizing the magnet M, causing it to draw the rod L and tongue J inthe opposite direction.

The armatures w are each provided with a longitudinal groove to admit ofthe introduction of oil into the magnets.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. .In an electrically-operated railway switch, thecombination, with the car and electromagnetic switch moving mechanism,of a contact-maker formed of a sliding springpressed rod, a fixedinsulated contact spring, a movable contact spring carried by. the rod,a yielding contact lever, and-contact plates, sub
